Utilizing the power of quantum physics, photonic quantum computers harness light particles (photons) for information processing, potentially surpassing traditional quantum computers in speed and long-distance data transmission.
“The appeal of photonic quantum computing lies in its ability to operate at room temperature with minimal decoherence,” explained Hui Wang, a co-author of the study, in an interview with Phys.org.
Despite its advantages, a key challenge is the limited interaction between individual photons, hindering the creation of essential two-qubit gates for scalability. To overcome this obstacle, the concepts of fusion and percolation have emerged in the field over the past two decades.
Research indicates that fusion and percolation offer scalable solutions for quantum computation in photonic systems without the need for deterministic entangling gates, unlike other technologies like superconducting qubits and trapped ions. Wang and his team demonstrated a strategy involving fusing small resource states, such as the heralded 3-GHZ state, into large-scale cluster states for measurement-based quantum computing.
“According to the percolation theorem, success is possible if the fusion gate’s success probability surpasses a specific threshold,” Wang emphasized.
